1985 is a 4t60 a Direct replacement for a 125 ? bolt up, axles, plug for lockup ??? if I have to rebuild one, I'd rather have overdrive. thanks

Bolts to block, can use factory GM brackets from 4T60, but need to move mounts inboard on cradle, passenger axle the same, different axle on driver side. Must modify shift cable bracket and arm, use adjustable shift cable.
Use Fiero kickdown cable.
Tap vacuum port in upper plenum for transmission vacuum solenoid.
